Teacher-student Interaction Research In Key Events In Junior High School Mathematics Classroom

Mathematics teaching is the unity of teachers' teaching and students' learning.It is a two-way process.Through the interaction between teachers and students,the realization of mathematics teaching process is a basic and effective way.In addition,the concept of junior high school mathematics curriculum emphasizes the interaction between teachers and students,and holds that classroom teaching activities are the process of active participation,interaction and mutual growth.Thus,the study of the interaction between teachers and students in junior high school mathematics classroom has an important significance and value to improve the teaching of mathematics in middle school.Therefore,this paper mainly studies the interaction between teachers and students in the key events in junior high school mathematics classroom.In the study,studying the related literature at home and abroad of teacher-student interaction,the collected literature data were collected and analyzed,the study of the interaction between teachers and students always have a certain degree of understanding,the author also makes the theory of the interaction between teachers and students have a certain understanding.First of all,the paper defines the key words in the paper,the key event,the relationship between teachers and students,the interaction between teachers and students in mathematics classroom.Secondly,according to the classroom teacher-student interaction evaluation system(CLASS)in the literature,the theoretical framework is obtained.In research methods,this paper uses the interview method and case study method,classroom observation method,the real situation the author comprehensively and objectively recorded a Shanghai city middle school mathematics classroom teachers 4 key events in the interaction.Two of them are teachers,and the other two are excellent teachers.Through the observation and analysis,we can find that the difference between the teachers and the teachers is obvious.The interaction between teachers and students in the class of excellent teachers is characteristic:1.Create rich classroom situation.In the real situation,teachers and students are more likely to communicate with each other.Open,autonomous,inquiry and dialogue teaching methods make the dialogue between teachers and students and the communication between students andstudents.2.A variety of situational presentation.The excellent teachers will use situation display method,practice experience method,knowledge transfer method,step by step method to show the situation,not only can stimulate students' interest,but also can better interaction between teachers and students.3.Give students more opportunities to explore independently.By allowing students to operate,practice,to provide students with scaffolding,as well as the question will be transformed into the content of knowledge to facilitate students to understand the interaction of teachers and students,student interaction.Let the students in the state of confusion and resentment,led him to learn to guess,reasoning,test,help him learn how to make decisions.4.Diversified activity representation.Students from a variety of ways to understand mathematics,but also to enhance the ability of mathematical communication between teachers and students.5.Positive feedback.Excellent teachers will be positive from the perspective of each student to improve their self-confidence.The following suggestions are put forward:1.Pay attention to the interaction between teachers and students.2.Creating democratic classroom,creating interactive atmosphere.3.Rich interactive way to increase the interaction of the main participants.4.Increase the proportion of students in the key events in the classroom.
